Diagnosis. Hoplosauris pachrophylloides is differentiated from other species in the genus by the androconia formed by a tuft of simple hairs and some thick bristles in the male genitalia. The valval costa is strongly sclerotized. In the female genitalia the microspines are present on the posterior half of the corpus bursae. This last character is an autapomorphy for the species.

Description. Male ( Figure 1b). Head: Antennae sub-apically thickened, covered by dark brown scales. Vertex and frons with dark and white scales. Labial palpi covered by scales with similar pattern to the forehead and vertex. Thorax: patagia and tegula covered by dark and white scales. Tegulae with enlarged piliform scales extending posteriorly. Forewings: upperside grey-brown. Basal line orange. Stripe, between basal and medial lines, dark brown. Medial line orange, surrounded by dark brown scales. Subterminal line orange. Terminal line formed by dark brown semicircles. Discal mark dark brown. Hindwings: reduced, with a hairy convex vesicle on the anal margin; upperside and underside white. Abdomen covered by white scales on its anterior region and dark grey scales towards its posterior region. Fore and second mid legs with white femur. Tibiae and tarsi with brown and white intercalated stripes. Hind legs white. Female. Head and thorax the same as the male. Forewings: upperside grey brown. Basal line dark brown. Middle stripe light brown. Medial line orange with its borders covered by dark brown scales. Subterminal line dark brown, with orange marks. Terminal line represented by dark brown semicircles. Discal mark dark brown. Underside light brown. Hindwing whitish. Without reduced hindwings and without a hairy concave vesicle on the anal margin. Legs: white, femur, tibiae and tarsi with intercalated dark brown and white scales. Male genitalia ( Figures 3a, c). Uncus curved, slightly setose, acute apex, basis subtriangular, approximately ½ the length of the valvae. Valvae sub-rectangular, with androconia at subapical position, androconia with some long and thick bristles. Costa strongly sclerotized. Ventral margin of the valvae with a small groove on its medium region. Saccus semicircular. Aedeagus, short stout, tubular, vesical with a group of long and fine spines, approximately 1/3 the length of the aedeagus. Female genitalia ( Figure 3b). Sterigma membranous. Corpus bursae elongated, tear drop shaped, membranous, slightly sclerotized medially, with microspines on its internal surface distributed medially and anteriorly. Ductus bursae approximately ¼ length of the corpus bursae. Anterior and posterior apophyses subequal. Ductus seminalis indistinguishable.

Distribution. This species occurs between the 36º S and 38º S, in the provinces of Ñuble and Cautín.

Etymology. The name refers to the similarity to species belonging to the genus Pachrophylla ( Larentiinae : Trichopterygini ).

Flight period. Specimens were captured during the months of January and March. There are no records from other months.
